From an aesthetic perspective, the show looks quite good. The characters look more crisp than the OVA version and the colours are more vibrant. However, it's hard to say if 1412 is strictly better than the OVA version in terms of art because the OVA had a bit of an old school charm to it. Also some of the CGI looks really out of place in 1412. The soundtrack of this show is honestly amazing. All of the opening and ending these can be contenders for the top 5 opening and endings themes of the season. The BGM ranges from some sappy jazz to quick beat rhythm that makes you want to move along with the action.
Now the problem with Kaito is that the story is quite repetitive. It's akin to the monster of the week shounen but with thefts. Though some of the ways Kaito solves his problems can be considered as bigger asspulls than No Game No Life, a lot of the more thought out ones, especially the ones involving Conan, are quite intriguing and will make you go "aha" afterwards. To me, the most important aspect of the show are the characters. Honestly speaking, the main characters Kaito and Aoko are quite stagnant and set in their tropes. However, there's no rule stating that stagnant characters cannot be loveable characters. Though Kaito can sometimes make you cringe with his white knighting neckbeard fedora M'lady act, he and Aoko both have a sort of charisma that makes you love them. They are especially adorable during the romance episodes albeit being a bit cheesy.
I would definitely recommend this anime to people looking to watch something lighthearted and have some fun. And I would definitely recommend it to Conan fans who haven't checked out the OVA version yet as this is the ultimate fanservice.
